fuel formulations; biennial review

HB 2401 requires Arizona's department to conduct a biennial review of fuel formulations available under federal air quality standards. The review assesses potential impacts of switching to non-authorized fuel types in "Area A" and "Area C" (defined in existing law), specifically noting anticipated air quality effects in those regions. By December 31 each review year, the department must submit a report with recommendations to the governor, legislature leaders, and other designated officials. This bill establishes a procedural requirement for ongoing evaluation of fuel options, without mandating specific fuel changes.
